Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a multi-station pneumatic machining fixture. Background Technology

[0002] Fixtures are a broad category of tools used in woodworking, metalworking, fitter work, machinery, electrical control, and other handicrafts. They primarily serve to assist in controlling position or movement (or both). With continuous technological advancements, the quantity and quality requirements of machining are constantly increasing, especially for the high precision requirements of machining parts. In the production of certain workpieces, drilling, boring, and milling are necessary. Currently, single-station or double-station clamping devices are commonly used to hold the workpieces during machining, resulting in slower processing speeds and requiring more clamping operations.

[0003] Currently, multi-station fixtures often cause problems such as excessive processing time for individual parts, leading to overheating and potentially affecting the strength and other physical properties of the workpiece. Utility Model Content

[0004] The purpose of this invention is to provide a multi-station pneumatic machining fixture in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A multi-station pneumatic machining fixture includes an equipment platform. The upper surface of the equipment platform is provided with a switching mechanism. The switching mechanism includes a cylinder, an outer ring rotatably connected to the outer side of the cylinder, and planetary plates arranged in a circular array fixedly connected to the circumferential surface of the outer ring. A sun gear is fixedly connected to one end of the cylinder, and a vertical plate is fixedly connected to the other end of the sun gear. The bottom end of the vertical plate is fixedly connected to the equipment platform. A planetary gear is rotatably connected to the end of the planetary plate away from the cylinder. The planetary gear meshes with the sun gear. The number of teeth of the planetary gear and the sun gear are equal. A power component is provided on the lower side of the cylinder. A clamping mechanism is provided on the side of the planetary gear away from the planetary plate. A locking mechanism is provided on the clamping mechanism.

[0007] Preferably, the power assembly includes a motor mounted on a vertical plate, and the output shaft of the motor is fixedly connected to a drive gear, which meshes with an external gear ring, and the external gear ring is fixedly connected to an outer ring.

[0008] Preferably, the clamping mechanism includes a mounting block, which is fixedly connected to a planetary gear. An L-shaped plate is fixedly connected to the side of the mounting block away from the planetary gear. A fixed clamping plate is fixedly connected to the end of the L-shaped plate near the planetary gear. A sliding sleeve is slidably connected to the L-shaped plate. A movable clamping plate is fixedly connected to the side of the sliding sleeve away from the sun gear. A cylinder is fixedly connected to the side of the movable clamping plate away from the fixed clamping plate. The other end of the cylinder is fixedly connected to the L-shaped plate. A locking mechanism is provided on the side of the sliding sleeve near the sun gear.

[0009] Preferably, the locking mechanism includes an L-shaped plate two, one end of which is fixedly connected to a mounting block, and the other end of which is fixedly connected to an L-shaped plate one. A ratchet rack is fixedly connected to the side of the L-shaped plate two near the sliding sleeve, and a locking component is provided between the sliding sleeve and the ratchet rack.

[0010] Preferably, the locking assembly includes a slider, which is slidably connected to a sliding sleeve. An electric telescopic rod is fixedly connected to one side of the slider, and the other end of the electric telescopic rod is fixedly connected to the sliding sleeve. A pawl plate is hinged to the slider, which engages with a ratchet rack. Connecting rods are hinged to both sides of the pawl plate, and the top of the connecting rod is hinged to the sliding sleeve.

[0011] Preferably, a cooling pool is provided on the upper surface of the equipment platform.

[0012] The beneficial effects are as follows: By installing a clamping mechanism on the planetary gear, the planetary gear revolves around a fixed external gear ring, and the clamping mechanism also rotates accordingly. If the workpiece and clamping mechanism on one side have a long processing time and generate significant heat, another workpiece and clamping mechanism can be switched to that side. Since the number of teeth on the planetary gears is equal, after the planetary gear completes one revolution around the ring, it will also rotate once on its own axis. The workpiece and clamping mechanism will return to their initial positions and angles. After cooling down through rotation, processing can continue, avoiding changes in the strength and precision of the workpiece caused by prolonged processing.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figure 1 - Figure 4As shown, a multi-station pneumatic machining fixture includes an equipment platform 100. The upper surface of the equipment platform 100 is provided with a switching mechanism. The switching mechanism includes a cylinder 301. An outer ring 302 is rotatably connected to the outer side of the cylinder 301. Planetary plates 304 arranged in a circular array are fixedly connected to the circumferential surface of the outer ring 302. A sun gear 303 is fixedly connected to one end of the cylinder 301. A vertical plate 309 is fixedly connected to the other end of the sun gear 303. The bottom end of the vertical plate 309 is fixedly connected to the equipment platform 100. A planetary gear 305 is rotatably connected to the end of the planetary plate 304 away from the cylinder 301. The planetary gear 305 meshes with the sun gear 303. The number of teeth of the planetary gear 305 and the sun gear 303 are equal. A power assembly is provided on the lower side of the cylinder 301. A clamping mechanism is provided on the side of the planetary gear 305 away from the planetary plate 304. A locking mechanism is provided on the clamping mechanism.

[0025] The cylinder 301 is used to connect the sun gear 303 and the vertical plate 309. The vertical plate 309 is used to connect the equipment platform 100. The outer ring 302 is used to rotatably connect the cylinder 301, so that the planetary plate 304 can rotate around the cylinder 301. The planetary plate 304 is used to mount the planetary gear 305. Due to the fixation of the outer gear ring 306, when the outer ring 302 rotates, it drives the planetary plate 304 to rotate, causing the planetary gear 305 to revolve around the sun gear. At the same time, the planetary gear 305 rotates on its own axis, driving the clamping mechanism to revolve around the sun gear and rotate on its own axis. Since the number of teeth of the planetary gear 305 and the sun gear 303 is equal, after the planetary gear 305 revolves around the sun gear once, it will also rotate on its own axis once. The workpiece and the clamping mechanism return to their initial positions.

[0026] The power assembly includes a motor 308, which is mounted on a vertical plate 309. The output shaft of the motor 308 is fixedly connected to a drive gear 307, which meshes with an external gear ring 306. The external gear ring 306 is fixedly connected to an outer ring 302.

[0027] The motor 308 provides rotational power to drive the drive gear 307 to rotate. The drive gear 307 drives the outer ring 302 to rotate through the outer gear ring 306, which in turn drives the planetary plate 304 to rotate.

[0028] The clamping mechanism includes a mounting block 401, which is fixedly connected to a planetary gear 305. An L-shaped plate 402 is fixedly connected to the side of the mounting block 401 away from the planetary gear 305. A fixed clamping plate 403 is fixedly connected to the end of the L-shaped plate 402 near the planetary gear 305. A sliding sleeve 405 is slidably connected to the L-shaped plate 402. A movable clamping plate 404 is fixedly connected to the side of the sliding sleeve 405 away from the sun gear 303. A cylinder 406 is fixedly connected to the side of the movable clamping plate 404 away from the fixed clamping plate 403. The other end of the cylinder 406 is fixedly connected to the L-shaped plate 402. A locking mechanism is provided on the side of the sliding sleeve 405 near the sun gear 303.

[0029] Mounting block 401 is used to fix and connect L-shaped plate 402. L-shaped plate 402 is used to fix and connect fixed clamping plate 403 and sliding sleeve 405. Sliding sleeve 405 is used to fix and connect movable clamping plate 404. Under the push of cylinder 406, movable clamping plate 404 and L-shaped plate 402 complete the clamping of workpiece.

[0030] The locking mechanism includes an L-shaped plate 2 501, one end of which is fixedly connected to a mounting block 401, and the other end of which is fixedly connected to an L-shaped plate 1 402. A ratchet rack 502 is fixedly connected to the side of the L-shaped plate 2 501 near the sliding sleeve 405. A locking assembly is provided between the sliding sleeve 405 and the ratchet rack 502.

[0031] L-shaped plate 501 is used to install ratchet rack 502, which, under the action of the locking assembly, restricts and locks the sliding sleeve 405.

[0032] The locking assembly includes a slider 503, which is slidably connected to a sleeve 405. An electric telescopic rod 504 is fixedly connected to one side of the slider 503, and the other end of the electric telescopic rod 504 is fixedly connected to the sleeve 405. A ratchet plate 505 is hinged to the slider 503, which engages with a ratchet rack 502. Connecting rods 506 are hinged to both sides of the ratchet plate 505, and the top of the connecting rod 506 is hinged to the sleeve 405.

[0033] The electric telescopic rod 504 pushes the slider 503, which in turn causes the pawl plate 505 to slide. Because the pawl plate 505 is hinged to the connecting rod 506, the angle between the pawl plate 505 and the sliding sleeve 405 gradually decreases, causing the bottom end of the pawl plate 505 to leave the ratchet rack 502, thus completing the release and engagement.

[0034] The upper surface of the equipment platform 100 is provided with a cooling pool 200.

[0035] Cooling pool 200 is used to cool the workpiece at the bottom.

[0036] Working principle:

[0037] The workpiece is placed between the moving clamping plate 404 and the fixed clamping plate 403. The cylinder 406 is activated to push the moving clamping plate 404 closer to the fixed clamping plate 403, thus completing the clamping of the workpiece. After each clamping device has clamped the workpiece, the workpiece on one side is processed. When the workpiece overheats, the motor 308 is activated to drive the drive gear 307 to rotate, which in turn causes the outer gear ring 306 and the outer ring 302 to rotate. This causes the planetary plate 304 and the planetary gear 305 to revolve around the sun and rotate on their own axis at the same time. This allows the overheated workpiece to be rotated away, and the other workpiece and the clamping mechanism can then be moved to the same side for further processing. Since the number of teeth on the planetary gear 305 is equal, the planetary gear 305 will rotate on its own axis after one revolution around the sun. The workpiece and the clamping mechanism will then return to their initial positions and angles. After the workpiece has cooled down due to rotation, processing can continue.

[0038] A cooling pool 200 is provided on the equipment platform 100. Overheated workpieces can be initially cooled in the air after leaving the processing side. When switching over again, they can enter the cooling pool 200 for further cooling, which facilitates continued processing.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
